Add header for _Float32 testing.

Browse Source 
This patch adds the header required for testing _Float32 function
aliases, using float ulps.  The corresponding makefile support will be
included in the main patch that enables those aliases.

In conjunction with other _Float32 changes, tested for x86_64 and with
build-many-glibcs.py.

	* math/test-float32.h: New file.
